    --[[    #### Important note when dealing with -0 and infinity ####

    1. Dealing with infinity is consistent, the only difference is whether the resulting 0 is integer or float

    Lua 5.3: dividing by infinity yields float 0
    With inf = 1/0:
        -inf    = -inf
         1/inf  =  0.0
        -1/inf  = -0.0
         1/-inf = -0.0
        -1/-inf =  0.0

    Lua 5.2 and 5.1 and luajit: dividing by infinity yields integer 0
        -inf    =-1.#INF
         1/inf  =  0
        -1/inf  = -0
         1/-inf = -0
        -1/-inf =  0

    2. Dealing with minus 0 is totally inconsistent mathematically and accross lua versions if you use the syntax -0. 
       It works correctly if you create the value by minusZero = -1 / (1/0)

       Enable the function above to see the extent of the damage of -0 :

       Lua 5.1:
       * -0 is consistently considered as 0
       *  0 multipllied or diveded by -1 is still 0
       * -0 multipllied or diveded by -1 is still 0

       Lua 5.2 and LuaJIT:
       * -0 is consistently -0
       *  0 multipllied or diveded by -1 is correctly -0
       * -0 multipllied or diveded by -1 is correctly 0

       Lua 5.3:
       * -0 is consistently considered as 0
       *  0 multipllied by -1 is correctly -0 but divided by -1 yields 0
       * -0 multipllied by -1 is 0 but diveded by -1 is -0
